You'll Build a Healthier Heart
Most people aren't used to pushing into the anaerobic zone (that lovely place where you can't breathe and you feel like your heart is trying to jump out of your chest). But in this case, extreme training produces extreme results. One 2006 study found that after 8 weeks of doing HIIT workouts, subjects could bicycle twice as long as they could before the study, while maintaining the same pace. 

You'll Increase Your Metabolism
In addition to increased fat burning and more muscle preserved, HIIT stimulates production of your human growth hormone (HGH) by up to 450 percent during the 24 hours after you finish your workout. This is great news since HGH is not only responsible for increased caloric burn but also slows down the aging process, making you younger both inside and out!

The format we use is High Intensity Interval Training (HIIT), the no. 2 fitness trend in the world, according to the 2015 American College of Sports Medicine's Worldwide Survey of Fitness Trends. This format offers seasoned exercisers a new challenge and new exercisers a quick way to see results. You definitely won't be bored!  HIIT describes any workout that alternates between intense bursts of activity and fixed periods of less-intense activity or even complete rest. It sounds too simple to be effective, but science doesn't stretch the truth.

So what are the advantages?
Intervals of aerobic HIIT have been shown to increase VO2max (the highest amount of oxygen a person can consume during maximal exercise, ultimately a measure of your cardio-respiratory fitness level) compared to continuous aerobic training, even though HIIT workouts take less time to complete. Furthermore, a 2013 Journal of Strength and Conditioning study found that four weeks of HIIT workouts burned more body fat than traditional workouts. Effective HIIT training will help you torch calories, build lean muscle, lose fat, improve heart health, push your limits, and increase efficiency.

It's Efficient
Super-efficient HIIT is the ideal workout for a busy schedule—whether you want to squeeze in a workout during your lunch break or to get in shape for a fast-approaching event. Research shows you can achieve more progress in a mere 15 minutes of interval training (done three times a week) than the girl jogging on the treadmill for an hour.  And according to a 2011 study presented at the American College of Sports Medicine Annual Meeting, just 2 weeks of high-intensity intervals improves your aerobic capacity as much as 6 to 8 weeks of endurance training.

Quick And Convenient
Long gone are the days of not having enough time for exercise. HIIT workouts can be done in 30 minutes or less! Who can’t spare that?

Why Is HIIT the Best Workout to Burn Fat?
Exercise physiologists used to believe that “steady state” cardio was superior for fat loss because relatively more fat is used by the body as fuel at lower exercise intensities than at higher intensities. The “Fat Burning Zone” shown on most cardio equipment as only 60%-65% of max heart rate is really a myth and is NOT optimal for burning fat. In addition, interval training allows you to exercise at very high intensities for a much longer period of time than steady state, additionally helping you to burn even more fat.

What does it all mean?

With all of that said, the real magic of HIIT lies in its ability to keep you burning fat even after you leave the gym. In short, your body isn’t able to bring in enough oxygen during periods of hard work. Therefore, you accumulate a “debt” of oxygen that must be repaid post-workout in order to get back to normal. The result: your metabolism is revved for hours after you leave the gym. Trainers refer to this phenomenon as Excess Post-exercise Oxygen Consumption, or EPOC. You increase your metabolism and burn more calories for up to 24 hours after interval training, whereas going for a jog burns almost NO calories after the run.  Come join our fit family and see for yourself!
